Installation and Setup
Precautions
WARNING! All wiring must be performed by a qualified electrician
or instrumentation engineer. See diagram for terminal designa-
tions and wiring examples. Consult factory for assistance.
WARNING! Avoid shock hazards! Turn signal input, output, and
power off before connecting or disconnecting wiring, or remov-
ing or installing module.
Précautions
ATTENTION! Tout le câblage doit être effectué par un élec-
tricien ou ingénieur en instrumentation qualifié. Voir le dia-
gramme pour désignations des bornes et des exemples de
câblage. Consulter l'usine pour assistance.
ATTENTION! Éviter les risques de choc! Fermez le signal
d'entrée, le signal de sortie et l'alimentation électrique avant
de connecter ou de déconnecter le câblage, ou de retirer ou
d'installer le module.
Socket and Mounting
The module installation requires a protective panel or enclo-
sure. Use API 011 or finger-safe API 011 FS socket. See
specifications for maximum allowable socket voltages. Note
that some relay sockets may have lower voltage ratings. The
socket clips to a standard 35 mm DIN rail or can be attached
to a flat surface using the two mounting holes.
Signal Input
The input range is factory calibrated and does not require
adjustment. Polarity must be observed when connecting the
signal input.
If your transmitter has a current output, determine if it provides
power to the current loop or if it must be powered by the API
module. Use a multi-meter to check for voltage at the transmit-
ter output terminals. Typical voltage may be in the range of 9
to 24 VDC.
If your transmitter has a powered mA output, connect to
terminals 4 and 5.
If your transmitter is a passive device it can be powered by
the 18 Volt DC power supply at terminal 2. This may save the
expense of purchasing a separate power supply for the input
device. Connect to terminals 2 and 4.
Type of Input Device
– Terminal + Terminal
Sensor or transmitter with a voltage output.
Transmitter with a mA output that
provides power to the current loop.
Typically a 3 or 4-wire device.
Transmitter with mA output that is
unpowered. Typically a 2-wire device.
API module powers loop.
Relay Output Terminals
See wiring diagram for connections. The module does not
provide power to the relay contacts.
Inductive loads (motors, solenoids, contactors, etc.) will greatly
shorten relay contact life unless an appropriate RC snubber
is installed.
Module Power
Check model/serial number label for module operating voltage
to make sure it matches available power.
When using DC power, polarity must be observed. The positive
(+) must be wired to terminal 1 and negative (–) must be wired
to terminal 3.
Alarm Configuration
The relay operation is factory configured. The default configu-
ration is HI alarm normal acting. See model/serial number label
for non-standard relay configuration options.

Setpoint
This multi-turn potentiometer allows the operator to adjust the
level at which the alarm is activated. This control is adjustable
from 0 to 100% of the input range.
Deadband
The deadband potentiometer allows the alarm trip/reset win-
dow to be adjusted symmetrically about the setpoint from 1 to
100% of the span.
Deadband allows the operator to fine tune the point at which
the alarm trips and resets. The deadband is typically used to
prevent chattering of the relays or false trips when the process

To calibrate the alarm section, set the deadband control to the

Set the signal source to a reference that represents the desired
trip point.
Adjust the setpoint control to the point at which the relay
changes state from a non-alarm to an alarm condition.
If a larger amount of deadband is desired turn the deadband potenti-
ometer clockwise. The deadband is symmetrical about the setpoint;
both transition points will change as deadband is increased.
Alternately set the setpoint and deadband until the desired trip/
reset points are set.
Output Test Function
The functional test button toggles the alarm status independent of
the input when depressed. It verifies the alarm and system opera-
tion. When released, the relay will return to its prior state. This can
be used as a diagnostic aid during initial start-up or troubleshooting.
Output Calibration
The top-mounted zero and span controls allow recalibration of
the analog output if required. Calibration requires an accurate
signal source and measuring equipment, such as an accurate
digital voltmeter.
OFF
Set the signal source to the minimum desired input. Adjust the

process changes, check the module power or signal input wiring.
The red LoopTracker output LED provides a visual indication that the
output signal is functioning. It becomes brighter as the input and the
corresponding output change from minimum to maximum.
For current outputs, the LED will only light if the output loop
current path is complete. For either current or voltage outputs,
failure to illuminate or a failure to change in intensity as the
process changes may indicate a problem with the module
power or signal output wiring.
Note that it may be difficult to see the LEDs under bright light-
ing conditions.
The bi-color alarm LED provides a visual indication of the alarm
status. In all configurations, a green LED indicates a non-alarm
condition and a red LED indicates an alarm condition.
High Alarm (Standard)
The alarm relay changes state when the input exceeds the
deadband trip point. The relay resets when the input drops below
the deadband reset point unless the module has a latching relay
option. For a high alarm, the trip point is above the reset point.
Low Alarm (L)
The alarm relay changes state when the input goes below the
deadband trip point. The relay resets when the input exceeds
the deadband reset point unless the module has a latching relay
option. For a low alarm, the trip point is below the reset point.
HT Latching Alarm Option
The module has a latching alarm with a push button reset. The
Reset button or powering the module off can be used to reset
the alarm provided the alarm condition no longer exists.
HP Option
The module has a latching alarm with a power-off reset.
Module power must be turned off to reset alarms. The alarm
will reset provided the alarm condition no longer exists.
Normal Acting Alarms (Standard)
Normal acting alarms energize the relay coils in a non-alarm
condition and de-energize them in an alarm condition. This will
create an alarm condition if the module loses power.
Reverse Acting Alarms (R Option)
Reverse-acting alarms energize the relay coils in an alarm con-
dition and de-energize them in a non-alarm condition. There is
no alarm condition with module power off.
SPR Set Point Retransmission Option
With the SPR option, a transmitted signal (0-1 VDC) indicates
the value of the alarm setpoint. The output will track the adjust-
ment of the alarm setpoint potentiometer.
